SECTION 12: FLUE SPILLAGE MONITORING SYSTEM
Remote controlled fires are fitted with a flue spillage safety device (ODS).
If the fire shuts down during use for no apparent reason then several things may be
suspected, if a door or window has been opened creating a draught, then pilot disturbance is
the problem, and removal of the draught should resolve this.
The gas pressure reaching the fire must also be checked (again, recalls your installer to check
and rectify any problem).
The thermocouple connection into the back of the gas control valve may also have worked
loose during installation, simply get the installer to tighten.
If pilot disturbance is not the cause, then the ODS safety system may be in operation.
Switch the appliance OFF, check the flue and carry out any remedial work required.
Relight the fire and carry out a spillage test, DO NOT allow the appliance to be used if it
continues to fail a spillage test.
The aeration hole of the pilot must be carefully cleaned out on each annual service to ensure
continued function of the ODS.
The spillage monitoring system shall not be adjusted, modified, or put out of operation by the
installer.
Any spare parts fitted MUST be of a type supplied for the purpose by the appliance
manufacturer.
If the fire is not spilling, then further guidance should be sought, using the Troubleshooting
section as a guide.
SECTION 13: TESTING FOR SPILLAGE
Close all doors and windows to the room containing the appliance.
Let the fire run on HIGH for five minutes.
Take a smoke match, light it, and using a smoke match tube, hold it at the top edge of the
fire opening, 25mm down and 25mm in.
Run the smoke match across the opening, all the smoke should be drawn away up the flue.
Any smoke returning into the room indicates that spillage is occurring.
If the initial spillage test fails, run the fire for a further 10 minutes and repeat the test.
When the test has been completed satisfactorily, repeat with any extractor fans in the
premises running on the highest setting, and any communicating doors open.
Finally, repeat with all doors open.
DO NOT allow the fire to be used until the test is satisfactorily passed.
